摘要： A circuit protection system (100) includes a first current sensing device (102) operative to measure a current of a first phase of a voltage source (151), a second current sensing device (102) operative to measure a current of a second phase of a voltage source (153), and a logic portion (110) communicatively connected to the first current sensing device (102) and the second current sensing device (102), the logic portion (110) operative to receive measured currents from the first current sensing device (102) and the second current sensing device (102), determine whether the measured current of the first phase (151) is less than a threshold current value during a time period, and output an indication that a short exists in the first phase of the voltage source (151) responsive to determining that the measured current of the first phase (151) is not less than the threshold current value during the time period.
